摘　　要：模具中的螺旋面多经铣削而成,有些特殊的螺旋面,其廓形的曲线和直线间交接点处呈现尖点。如按光滑连接来设计计算铣刀刃形,则求出的铣刀刃形会出现刃形交错或分离现象。分析了这种刃形交错或分离的成因,并给出了分离部分的过渡刃形求解方法。Helical surfaces in molds are mostly shaped by milling. Some special helical surfaces, the interactions between its curvilinear profile and straight line profile are cusp points. If milling tool profiles are calculated and designed by smooth connection, the findings of milling tool profiles will appear profiles jagged or profiles detached phenomena. In the paper, the causes of profiles jagged or profiles detached are analyzed and solving method of transitional profiles of detached section is given.
